FEEDING DEVICE FOR BELT CON VEYERS.

Application filed December 14, 1925.. Serial No. 75,401.

This invention relates to feeding devices for belt conveyers, and moreparticularly to arrangements in such devices for feeding paper or otherflexible material to a iiapped belt, the flaps being employed forgripping the paper or other flexible material to the belt.

A long strip of paper, when conveyed through chemical solutions, becomeswet, and

Hi consequently, tends to increase in length. Because of the low tensilestrength of the paper it will tear when pulled through such solutions.It is in view of these difficulties that it has been found desirable toprovide (5 a fiapped belt in a conveying system for con veying paperthrough chemical solutions, the flaps of the belt being employed forgripping the paper to the belt.

One of the objects .of this invention is to provide a suitable devicefor feed1ng a long strip of paper to a flapped belt, wh ch device hasmeans associated therewith for spreading the flaps of the belt so thatthe.

paper may become flush with the surface of the belt before it is grippedby the flaps of the belt. It is also an object of the invention toprovide arrangements for releasing the flaps of the belt after the paperhas become flush with the surface of the belt.

While the nature of the invention Wlll be pointed out with particularityinthe' appended claims, the invention 1tself, both as to its objects andfeatures, Wlll be better understood from the detailed descriptionhereinafter following when read in connection with the accompanyingdrawing, in which Figure 1 shows a perspective of one possible feedingdevice suitable fora flapped belt conveyer; Fig. 2 is a longitud nalcrosssectionof the device shown in Fig. 1; and Fig. 3 shows onearrangement for supplying anew reel. of paper to the feeding deviceafter the old one has been completely a unwound. Similar parts will bedesignated 5 by similar reference characters wherever they appearthroughout the drawing.

One type of feeding device for a fiapped belt conveyer is shown atFig. 1. The base of this feeding device is designated by the referencecharacter 1. A rotatable reel 2, which has a long strip of paper orother flexible material wound thereon, is held between the end-bearingholders 3 and 4. The strip of paper 5 is unwound froin'the rotatwillappear more fully in the description hereinafter following. The movablebelt with the paper held thereon is shown at the left-hand side of thedrawing. a

A horizontal rotatable roller 8 is employed for aiding in pulling thepaper 5 unwound by the rotatablereel 2 to the movable belt. A pulley 9is on the same shaft as the horizontal rotatable roller 8 and has a belt10 thereon. The belt 10 connects the pulley 9 with another pulley 11,which may be similar in all respects to pulley 9. Pulley 11 is on thesame shaft as a horizontal rotatable roller over which the movable belt7 moves. The belt 10 is crossed so that pulleys 9 and 11 and,consequently, the horizontal rotatable rollers on the same shafts asthese pulleys, respectively, revolve in opposits directions as indicatedby the arrows on these pulleys.

In this device there is shown one arrangement for spreading the flaps ofthe movable belt 7 so that the paper 5, unwound from the rotatable reel2, may come in contact with the movable belt 7' before the flaps releaseto grip the paper. For accomplishing this there are two verticalrotatable rollers, 12 and 13, which are suspended by vertical bearingsin a bearing-holder 14., the details of which will be shown anddescribed in connection with Fig. 2. The lower surfaces of the verticalrotatable rollers 12 and 13 are very close to the surface of the belt,and they revolve in such a manner that the flaps of the movable belt 7are spread apart. It is due to these vertical rotatable rollers 12 and13 that the flaps are sufiiciently spread apart so that the paper 5,unwound from the rotatable reel 2, may come in contact with the surfaceof the movable belt 7. However, after the paper has come in contact withthe movable belt 7 the flaps are released so as to grip the paper firmlyLO the movable belt. It will be understood that while two verticalrotatable rollers have been shown for spreading the flaps of the belt,that they may be replaced by a single vertical rotatable roller ofsuitable diameter for accomplishing the same end.

Fig. 2 shows a longitudinal cross-section of the particular feedingdevice shown in Fig. 1. The rotatable reel 2 is unwound so that thepaper 5 may move over a slide 6, which is guided by the end projectionsthereof to the movable belt 7. The double pointed straight-line arrowsindicate the direction in which the paper 5 moves. The.

belt moves over the horizontal rotatable rollers 20 and 21 in thedirection indicated by the arrows on these rollers. The paper 5 movesbetween two horizontal rotatable rollers 8 and 23, to the movable belt7. The peripheral speeds of the horizontal rollers 8 and 20 must ofcourse be equal.

One of the vertical rotatable rollers 13 with its associated verticalsuspension bearing 24 is shown in this figure. One flap of the belt ismoved. up against the surface of the vertical rotatable roller 13 asufficient distance so as to allow the paper 5 to come in contact withthe movable belt 7. i fter the paper 5 has come in contact with themovable belt there may be means associated with the device for releasingthe flaps of the belt so as to allow the flaps to firmly grip the paper;but by the use of flapawhich are elastic and which tend to return totheir in itial positions, such additional means may not be deemednecessary. After the paper 5 has been unwound from the rotatable reel.2, the reel drops of its own weight through ashole in the base 1, aswill be shown more fully hereinafter. i

Fig. 3 shows arrangementsfor replacing a reel after the paper thereonhas been completely'unwound. In this figure the rotatable reel 2 is heldin place between end bearings which are fastened in bearingholders 3 and1, respectively. The paper 5 moves over the horizontal rotatable roller25 to the slide in the direction indicated by the double-pointed arrow.After the paper 5 has been completely unwound from the rotatable reel 2,a new reel 31, must then be moved into place. This new reel 31- is movedagainst two projections 32 and 33, which move outwardly when the newrotatable reel 31 is about to be put in place be tween the hearings inthe bearing-holders 3 and 1. Four springs, 34, 35, 36 and 37, areassociated with the projections 32 and 33, two of these, 3 1 and 35,being associated with the projection 32, and the other two, 36 and 37,being associated with the projection' 33. As the projections 32 and 33move outwardly the springs 34 anc 35, 36 and 37, move outwardly andbecause of the con nection of the springs 34 and 36 with thebearing-holders 3 and 1, respectively, these bearing-holders 3 and 1 andthe end bearings held thereby, are also moved outwardly. The projections32. and 33 are'so proportioned that the new reel 31, when almost inposition, causes the end bearings to be moved outwardly a sufficientdistance so that the rotatable reel 2 may drop through a hole in thebase 1. After the reel 2 has dropped, the new reel 31, having the paperwound thereon, moves into place, and the projections and 33 moveinwardly to their initial positions so that the end bearings, held inthebearing-holders 3 and 4, project into a hole in the center ef therotatable reel. 31. The springs-3 rto 37 may be made of phosphor bronzeor other springy malcial.

It will be understood that while only one type of a feeding device for abelt conveyer has been shown and described herein in con- I nection withthis invention, the invention is not limited to the particular type ofdevice show and described, but the invention may be embodied in otherand widely varied organizations without departing from the spirit of theinvention and the scope of the appended claims.
